Application filed April 14, 1922.

This invention relates to talking machines and has for its primary object an improved means of holding the reproducer needle in position in the reproducer such that the same can readily be removed without the use of the usual screw clamp as now generally employed in a number of talking machine reproducers,

Another obj cct of this invention is to provide a reproducer needle holder with a needle clamping means which consists of a cam positioned on the needle holder and ar ranged to clamp the needle in a firm position in the holder.

With these and many other objects in vi w which will be more readily apparent as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts as will be hereinafter fully pointed out illus trated and claimed.

It will be readily apparent to those skilled in the art to which this invention belongs that the same is susceptible to some struct-ural change and modification without departing from the spirit or scope of the invention, but a preferred and practical em bodiment of the invention is shown in the accompanying drawings in which-- Figure 1 shows a plan view of a reproducer of a well known make having my improved needle holding means applied. thereto.

Figure 2 shows an elevational view of the parts shown in Figure 1 of the drawings.

Figure 3 shows an enlarged front elevational view of a reproducer bar used with the reproducer shown in Figure 1, and shows my improved needle clamping means in the unclamped position, which is the position taken when removing the needle.

Figure t shows an edge view of the parts shown in Figure 3 and shows the position of the cam clamp when the needle is ready to be placed on the surface of the record.

Figure 5 is a plan view of a needle bar having the needle clamping device removed.

Figure 6 is an edge view of the parts shown in Figure 5 of the drawings.

Figure 7 is a plan view of the needle clamping bar whichis shown in operative position in Figure 4: of the drawings.

Figure 8 shows an elevational view of the TALIIING-MAGI-IENE REPRODUCER.

view of the combined ca a and clamping lever shown in operative position in Figure a of the drawings;

Similar reference numerals refer to similar parts throughout the several figures of the drawings.

in carrying out this invention no change is contemplated in the usual type of reproducer or the tone arm to which it is attachec the changes that i make to secure the imrovements in the method of holding the needle being confined to the needle bar designated in its entirety by the numeral 10.

The bar 10 is provided with the usual diaphragm pin point 11 and fulcrum arms 12, each of which is adapted to be engaged by a pin 13 as shown in Figure 2 of the drawings.

The needle bar 10 is further provided with a plurality of upstanding wings 14.

each of which is perforated with an open ing 15 through which there is adapted to pass a pin 16, upon which there is fulcrumed a combined lever and cam designated by the numeral 17 which is shown in operating clamped position in Figure 4 of the drawlngs.

The clamping surface of the cam is adapted to have a sliding engagement with a combined guard and clamping bar 18 to which is attached a needle engaging element 19. The bar 18 is provided with a perforation 20, through which there is adapted to pass a screw 21 or similar holding device used for holding the bar 18 to the needle bar 10.

When it is desired to remove a needle from the needle bar the end .22 of the clamp 17 is thrown down as shown in Figure 3 of the drawings, at which time the engaging bar 19 is released from the needle and the same free to be drawn away from the needle bar. The needle when clamped in place, occupies a position between'the bar 19 and the groove 23 of the needlev bar as shown in Figure 3 of the drawings.

This device obviates the use of the usual set or thumb screw that is employedin a variety of reproducers and greatly facilitates the interchange of needles which is a desirable feature on all machines wherein the needles are replaced frequently as is the Columbia, and a nuim Having thus described my invention What I claim and desire to secure by Letters Patent is- In a stylus bar for sound reprodncers, a needle holder formed at one end of said bar and comprising apair of laterally offset spared pivot wings bent up from the body of the bar and providing a needle receiving groove therebetween a resilient needle engaging nieniber fastened to said bill at the inner end of the groove formed between said Wings and arranged between said wings to frieiiionailly grip a needle and a (11m. pivot ally mounted between said wings and adapted to Contact with said resilient needle engaging member to force the same inlo holding engagement with a needle.

In teelzinioi'iy whereof llO allixes lii'sig nzxture.
